Loulu Diversity and Identification Workshop

Loulu, Hawaiʻi’s only native palms, were once a dominant plant of low elevation Hawaiian ecosystems and hold deep cultural connections. There are more than 20 endemic loulu species, all in the genus Pritchardia, and many are found on only a single island. The invasive coconut rhinoceros beetle (CRB) poses a serious threat to loulu. This workshop taught by NTBG Research Associate Dr. Susan Fawcett offers members of the conservation community the opportunity to learn about loulu diversity and how to identify these palms. A presentation on distinguishing morphological traits of loulu will feature photos from the field and an overview of trait variation and distinguishing characteristics. Following the presentation will be a hands-on opportunity to examine and compare fresh material from the comprehensive living collection at the National Tropical Botanical Garden, and a discussion of taxonomic questions that are the subject of ongoing research. In the afternoon, we will tour the living collection and examine traits in the field. We’ll meet with the Lāwaʻi Gardens horticulture team to discuss the current best practices for protecting loulu from CRB.

This workshop is free. Please note participants are responsible for all transportation (including airfare and vehicle rentals), accommodations, and meals. Registration is required and attendance is limited. To register or for more information, please contact Katie Magoun (kmagoun@ntbg.org) with your name, organization and position title (if applicable), and email. Deadline to register is Thursday, April 30, 2026.
